Sash-supporter



UNITED STATES PATENT OEEICE.

W. O. MCGILL, OF CINCINNATI, OHIO.

SASH-SUPPORTER.

Specification forming part of Letters Patent No. 49,541, dated August 2Q, 1865.

To all whom t may concern .l

Be it known that I, XV. O. MCGILL, of Oincinnati, in the county ot' Hamilton and State ot' Ohio, have invented a new and useful Improvement in SaslrSupporters; andI do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the accompanyingdrawings, malring part ot' this specification, in which- Figure l represents a side view of two sash in a frame with one side of removed. Fig. 2 represents a front view ot' a window-easement n ith two pieces of wood to representsash locked together with the improved supporter. Fig. 3 is a top view or a detached fastener.

Similar letters ot' reference indicate corre sponding parts in the drawings.

To enable others skilled in the art `to l'uily understand and construct my invention, I will proceed to describe it.

The parts marked A represent the casement or lrame ot' a window. (l, Fig. 1, is a partingbend between the sash. The parts marked B are represented as the sash, one elevated from the window-sill and the other depressed and made fast by means ot' a screw-bolt, D, working in a stationary frame, F, fastened to the top ofthe lower sash, in connection with and terminating in a recessed plate, H, placed in the upper sash, B, in connection with the bolt D and stationary frame F, a movable slideplate, G, with an elastic roller, E, attached, to be regulated by having the screw-bolt D pass through itfor the purpose of pressing the roller against-the upper sash, causing friction enough to sustain both sash in any position desirable; or the screw-bolt may be forced through far enough into the recess-plate H to lock bothsash in any position.

The advantage obtained by the operation v and construction of this device is that the screw-bolt D serves as adouble purpose: First, it serves to lock both sash in any position siniply by screwing the bolt D through fra-ine F into the recess in plate. H in the upper sash, and in the adjustment of the friction-roller E that is attached to the movable plate G. The end ot' plate at G is turned at right angles from the roller to allow thc bolt D to screw through it, and in so doing` the position ot' plate G must be determined by turning bolt D through plate G at the exact point to allow desirable pressure of roller against the upper sash before the bolt- D enters the rear part of stationary frame F, as thc position ot' plate G and roller E will not be changed by the turning the bolt D in either direction after it has passed through the rear part of the stationary frame. The roller E may be placed in any position desira ble for pressure previous to the bolt D being screwed through both parts of stationary frame F.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

A friction-roller made ot rubber or other elastic substance, in combination with screwbolt D and movable plate G and trame F, to regulate the same at will, operating as and for the purpose specified.
